ZombieMod 4.0

ive got that already its mainly the zip contents i dont know were to put: i got all the required files i just need to have it run (correctly).

yes ive all ready read the FAQ sheet and its provided link but i dont really understand it; im not a huge uber haxor, so thats why im asking for help.

i have the correct zombie mod files downloaded and i have them pasted in the correct area in the steam files. i just need to know what to do from there.
